Abstract

The present investigation was carried out to study the production performance of different poultry layers at Poultry Research Training Center, SVPUA&T, Modipuram, Meerut. Total 300 poultry layers of three breeds viz., Aseel, Kadaknath and Rhode Island Red in four nests were observed. The traits studied were age at sexual maturity, body weight at sexual maturity, annual egg production, egg weight, shape index, shell weight and shell thickness. The data were analysed by using CRD. The age and body weights at sexual maturity were 187.09±0.16, 182.54±0.15 and 160.21±0.15 days and 1441.74±0.58, 1287.94±0.49 and 1269.93±0.58 gm; the annual egg production and egg weight were 87.14±0.15, 105.32±0.27 and 229.19±0.70 eggs and 47.09±0.13, 42.57±0.41 and 52.42±0.11 gm; egg shape index 75.64±0.12, 75.01±0.11 and 74.67±0.15 per cent, shell weight 5.83±0.19, 5.74±0.01 and 7.08±0.18 gm and egg shell thickness 0.32±0.001, 0.33±0.001 and 0.32±0.001mm in Aseel, Kadaknath and Rhode Island Red breeds, respectively. The analysis of variance showed highly significant differences among breeds for most of the traits except egg shell weight and egg shell thickness.cc
